I asked a simple question about light and heat on this forum. It was immediately met with snarky and sarcastic comments… The helpful stuff came later. Eventually it moved from ‘why don’t you learn physics’ to some properly useful and technically advanced advise on increasing luminance without increasing heat.

People also assumed I was a beginner (I’m one of the world’s most published photographers).

There are some great minds here, but you have to take the good with the bad!
